1. The problem statement, all variables and given/known data [PLAIN]http://postimage.org/image/bd4pyoqkt/ [Broken] Make a sketch of Vout vs Vin for Vin from 0 to 5 V, assuming that both diodes have a diode drop of 0.5 V 2. Relevant equations None that I know of. 3. The attempt at a solution The way I see it, the Vout will start at 2V, since that's above the diode drop voltage, and that's what the middle battery is providing. But as I increase Vin, it will just keep increasing Vout as the current flows directly to Vout. Why would it take the other path with the diodes?
